Abstract

The development of gluten-free noodles using gembili flour offers an alternative solution to reduce Indonesia's heavy reliance on wheat flour while anticipating various health issues related to gluten consumption. This research aims to identify the physicochemical characteristics of gembili flour from five local varieties and to identify the varieties with the most potential for developing gluten-free noodles. Physicochemical characterization of flour includes measuring proximate, crude fiber, and amylose levels as well as flour pasting profile. The best varieties are identified through a theoretical approach based on the physicochemical properties of flour, especially amylose content, setback (ST), and final viscosity (FV), which are used as selection indicators. Empirical proof was carried out by measuring the cooking loss (CL) of noodles to verify the theoretical approach. The physicochemical properties of flour and CL of gembili noodles are greatly influenced by differences in varieties, except for gelatinization temperature and peak time. The Fufulu, Kapok and Kapok Kayanik varieties have high values and are not significantly different in the three selection indicators. The three varieties exhibited amylose, ST, and FV levels of approximately 23%, 204.5-276.50 cP, and 724.5-1012.5 cP, respectively. GT-Biplot analysis shows that only the Kapok and Kapok Kayanik varieties are the best varieties because they have a strong and positive relative position for the three selection indicator variables and a very negative relative position in contrast to CL compared to the other three local varieties. The Kapok variety was chosen as the best variety because it is superior in terms of nutrition and availability of raw materials compared to the other four varieties. The Kapok variety has amylose content, ST, FV, and CL of 23.19±0.34 %, 276.50±3.54 cP, 1012.5±71.4 cP, and 19.78±0.66 %, respectively.

Abstract

Jack bean is one of the alternative protein sources, with a protein content of 27.4% on a dry basis. The production of jack beans in Indonesia reached 12 tons/ha, with an average of 7 tons/ha. The utilization of jack bean for food was not optimal because it contained cyanide acid (HCN). For optimal utilization, jack bean must be transformed into low-HCN jack bean flour. HCN levels could be reduced to safe limits through food processing, namely by soaking and thermal treatment. The purpose of this research was to study the effect of jack bean pretreatment (no soaking, water soaking, or NaHCO3 soaking) followed by heat treatment (boiling or roasting) on HCN levels, proximate content, and physical characteristics of jack bean flour. Peeled jack bean is given a soaking treatment (without soaking, soaked in water for 24 hours, and soaked for 24 hours in NaHCO3 1%), followed by boiling for 60 minutes or roasting for 30 minutes, then dried and ground. The jack bean flours is analyzed for HCN content, water content, ash content, fat content, protein content, and carbohydrate content, as well as the degree of whiteness and aw.. This study showed that soaking treatment for 24 hours followed by boiling for 1 hour could reduce HCN levels to 4 mg/Kg, but roasting treatment could increase HCN levels in jack bean flour compared to the control. Pretreatment had a significant effect on water content, ash content, and fat content, while protein and carbohydrate levels had no significant effect. There was no difference in the degree of whiteness except for the roasting treatment, while the water activity decreased significantly in the range of 0.2-0.5 and lower than without treatment

Abstract

Jali (Coix lacryma-jobi L.) is a promising food crop in Indonesia, but its contribution to food security needs more improvement. This research aimed to analyze physico-chemical characteristics of native jali flour and its modified flour after treated by heat moisture treatment (HMT) and autoclaving-cooling (AC) method, and finally observe their effects on breakfast meal flakes (BMF). Both native and treated flour were analyzed for degree of whiteness, swelling power, solubility, water absorption index (WAI), water holding capacity (WHC), and gelatinization profile. HMT-modified jali flour exhibited solubility of 7.77%, gelatinization temperature of 74.95 °C, and peak viscosity of 3255 cP while amylose and resistant starch content reached 20.50% and 6.27%, respectively. Meanwhile, AC-modified jali flour showed lower solubility (4.13%), higher gelatinization temperature (76.15 °C), peak viscosity of 3220 cP, with amylose content of 22.30% and significantly higher resistant starch content (13.93%). Due to its superior resistant starch content, AC-modified Jali flour was selected for BMF formulation. The formulation was optimized through D-optimal with independent variables of 50−100% jali flour and 0−50% sorghum flour. As a result, the optimum formulation was obtained with a desirability value of 0.713, consisted of 100% jali flour without added sorghum flour. The optimized BMF had resistant starch 11.46%, rehydration capacity 58.48%, and hardness 415.12 gf. The product has the potential to diversify healthy breakfast options for community and may contribute to diabetes prevention.

Abstract

Instant sorghum rice is produced through cooking, freezing, and drying processes, resulting in a porous structure that allows for easy rehydration. This research aimed at developing an alternative method for instantizing sorghum rice using a combination of fluidized bed dryer (FBD) technique and glycerol addition. The samples were evaluated, including physical characteristics, consumer acceptance, and nutritional value information of selected product. Sorghum seeds were polished for 30, 45, and 60 sec, and their whiteness degree was recorded. Subsequently, the seeds were washed, pre-cooked with the addition of glycerol (0, 2, and 4%), steamed, frozen, and finally dried. The cooked sorghum rice was frozen in a freezer for 24 h at -20 °C and dried with a fluidized bed dryer until a constant weight was achieved. The addition of glycerol did not affect panelist’s acceptance for color, texture, taste, aroma and overall attributes (at significance level of 5%), and therefore, the treatment without glycerol was selected for further steps. The selected treatment exhibited the physical characteristics as follow: rehydration time (7.5 min), bulk density (0.41±0.03 g/mL), water absorption (41.92±0.50%), rehydration ratio (3.58±0.02) and volume expansion ratio (223.72±12.94), indicating that it meets the criteria for instant food. The nutritional value per 60 g serving size was as follows: total energy (240 kcal), protein 3 g (6% of Recommended Dietary Allowance (RDA)), total fat 0 g (0% RDA) and carbohydrate 56 g (17% RDA).

Abstract

Chicken satay is one of the signature dishes from Ponorogo Regency, often used as souvenirs by travelers. However, its short shelf life has limited the marketing and distribution area of the product. The activity aimed to train small enterprise partners in Ponorogo Regency to preserve their chicken satay using a simple commercial sterilization method and to measure the thermal process adequacy. The thermal process adequacy measurement was carried out at the SEAFAST Center, while the training was conducted in person at the partner's locations in Ponorogo. A questionnaire was distributed during the training to assess the participant's understanding of preserving food products using the thermal process. The sterilization process was performed by heating chicken satay in a pressure cooker for 1 hour (calculated since the maximum pressure cooker's temperature was reached), resulting in F0 values ranging from 4.2 to 5.2 minutes. The training was delivered by providing theoretical and practical experience. Data from questionnaires showed that the training improved the participants' understanding, with the average score per participant increased from 6.13 to 10.92 (32% increase).

Abstract

Coffee is widely and regularly consumed in Indonesia. The trend towards practical lifestyle has driven the development of ready-to-drink (RTD) coffee products. Avocado and durian are commonly incorporated as additives due to their unique flavor profiles, creamy textures, and potential to enhance the functional properties of coffee-based drinks. This study aimed to identify the optimal formulation of RTD avocado coffee milk and durian coffee milk products based on sensory characteristics and to estimate their shelf life using the direct method. The formulations were developed by varying the fruit purée concentration: 5%, 7.5%, and 10% for avocado coffee milk, and 5%, 10%, and 15% for durian coffee milk. The hedonic rating test revealed that formulations containing 5% avocado purée and 15% durian purée were the most preferred by 50 panelists. These selected formulations were further analyzed to estimate product shelf life at 4°C and 18°C. Quality changes were evaluated through objective parameters (color change [∆E], pH, viscosity, and physical stability) and subjective parameters (color, aroma, and flavor intensities). Products stored at 18°C deteriorated more rapidly and were excluded from further shelf life prediction. The estimated shelf life of avocado coffee milk stored at 4°C was 59 days based on flavor parameter (R² = 0.9338), while durian coffee milk had an estimated shelf life of 61 days based on pH (R² = 0.9305).
